Aqua TruDense™

The Aqua TruDense™ system is a Densified Sludge Treatment technology that combines all the features and benefits of a true batch SBR system, with the intensification of densified sludge. It features faster settling with increased MLSS concentrations, allowing for enhanced treatment in smaller footprint compared to activated flocculent sludge.

• Faster and reliable settling allows for additional treatment time compared to Activated Sludge
• Typical SVI 60 – 80 mL/g allows for fast settling of 5,500 – 6,000 mg/l MLSS
• True-batch system featuring a time-based control strategy provides ultimate treatment flexibility
• Intensified treatment allows for enhanced BioP removal and increased nitrification capacity
• Nutrient removal in a single tank compared to multi-stage BNR which need selector, anoxic, and aerobic basins
• No sludge recirculation, no physical selection devices (i.e. hydrocyclones), no carriers (i.e. plastic, magnetite, etc), and no primary or secondary clarifiers to build and maintain
• Uniform and controlled innovative selective wasting. Efficient surface wasting of lighter particles
• All accessible or retrievable equipment (including diffusers) for ease of maintenance

• Allows for additional treatment capacity in the same footprint as conventional activated sludge systems:
  • 55 – 65% additional flow and loading compared to conventional activated sludge systems
  • 20 – 25% additional flow and loading compared to batch activated sludge systems
• True batch in combination with faster settling sludge, allows for the system to be less susceptible to “wash out” of mixed liquor during storm flow events
• Increased ability to control process with control of D.O. level, mixing, settling and clarification in the same basin.
• Easily modify system to adapt to more strict effluent requirements (i.e. Modify cycle structure based on incoming flows and loading variation)
• Separation of aeration and mixing for enhanced control of environment, as well as power savings
